Unable to Unlock OEM - OnePlus 2 Q&A, Help & Troubleshooting

1-I Installed TWRP
2- I installed custom ROM CM 13
3-I need to update my custom ROM so i entered fastboot i found that OEM is disabled so i have to reboot to enable OEM unlocking
4-something happens so that i can't reboot to normal OS as power button doesn't make any response, i can only start fastboot using power and volume up, power and volume down doesn't make any response.
so the question is i need a way to install any thing that make my phone boot to OS regardless any thing (Formating ,.....)
Noting that:-
1-I can't use any (flash,erase,format,...) as OEM is locked.
2-I can't unlock OEM as it is disabled.
3-flashboot continue result device shutdown.
4-I am in a country that doesn't any support to oneplus devices.
Thanks in advance

How can you have a locked bootloader if you've already flashed a custom ROM? I'm not sure I understand what's going on - if you're able to boot into Android, there should be an option in the Developer Options menu to allow OEM unlocking. Again, I'm not sure if I understand what's going on but if you're able to access the bootloader (fastboot) you can flash the stock ROM found here: http://downloads.oneplus.net/2016-02-26/op2/OnePlus_2_OxygenOS_2.2.1/
I hope this helps!

Five cents he upgrade to OOS3 or MM H2OS with newer bootloader and failed to upgrade TWRP to compatible one with the bootloader, just like other thread 99% similar to this one, that I already answered to.

Revert back to locked state after unofficial unlock (Redmi note 3 pro/SD)

Hi All, I have unlocked the bootloader the unnofical way and i am on global 7.1.7.0(LHOMICL) with twrp and root.
I now have recieved the official sms to unlock from xiaomi.
Already i had to open the phone 3 times to get into edl mode. I really dont wont to open the phone agian.
When i try to unlock the tool answers no need to unlock. I think this is because i flashed the adapted emmc_appsboot.mbn and boot.img thru fastboot.
Do i have to change te rom to another version before i try thru edl or fastboot? What is the best procedure to official unlock now because i read a lot of bricks if they try to revert back to original state.
Can some one give me a detailed guide? Thanx in advance.
You need to flash a fully stock edl ROM on top of your current setup.
This will wipe out your hacked bootloader and throw the original (still locked) one back onto your device.
Then just unlock as usual. I did the procedure myself today already as I got my unlock notification today as well.
Ok thnx for the info. I have changed this global rom 7.1.7.0 in great extend and dont wont to lose this setup.
So can I backup my current setup with twrp with the hacked bootloader.
Flash the complete global 7.1.7.0 in edl mode. Unlock with the unlock tool.
Root the rom and install twrp.
After this can i restore the backup with the hacked bootloader with twrp?
I dont know how the unlock tool of xiaomi works, so i could leave the official bootloader in place when i do the restore with twrp and only replace system and data partition or can i flash all the parts back with twrp to keep the unlock?
Wich procedure will keep the official unlock in place or will this unlock stick always?

please give a detailed tutorial how to do it. I am now in AOSP with unofficially unlocked bootloader. How to relock it again to unlock officially?
Relock Bootloader
I see many asking how to Relock Bootloader, especially those who had unlocked unofficially.
The steps to be followed are following:
(1) Turn on USB debugging for your phone;
Go to Settings -- About Phone --> Touch 7 times on "MIUI version" to Enable Developer Options.
Now go to Settings - Additional Settings - Developer Options --> USB debugging.
Enable USB Debugging and Connect to PC.
(2) Download Fastboot ROM (file extension .tgz or .tar) from
Code:
http://en.miui.com/a-234.html
(3) Boot into EDL
adb devices (to check it's connected)
adb reboot edl
(4) Use MI Flash Tool to Flash the Fastboot ROM
PS: It is assumed that person knows how to get drivers installed for phone if not already, use ADB command as well as know MI Flash Tool basics.
@BRoy_98 @ioosis @davegrond : hope this helps.
@MrColdbird Thanks for the tip

On MiFlash, select folder of Fastboot ROM, then click on Advanced, and in fastboot script select flash_all_lock.bat. After it, close MiFlash then open it again and check in advanced if flash_all_lock.bat comes selected. If yes, close advanced box and flash ROM. Don't forget to close and open MiFlash after choose flash_all_lock.bat script, it's important step. And you can do it in Fastboot mode, don't need to go to EDL mode to flash the ROM.

warranty
does rooting redmi note 3 void warranty bcuz it has a locked bootloader and cannot root without unlocking it ????
and can we lock bootloader again for warranty claims ????
plzz help ???
ty.
Why can't we directly update the device..
Like after flashing miui ROM (7.1)then installing (8.1)....will the bootloader get locked....
?....somebody have any idea place help out
Q. Can the device be rooted without voiding warranty?
A. Yes, by unlocking the BL unofficially.
Q. Once rooted and on MiUI, can I update using Updater?
A. No! You'll lock your BL and end up in a bootloop. Instead, use the updater to download the zip file, reboot into recovery (TWRP or ZCX) flash the zip first and then the universal boot.img patched/lazy flasher and reboot to system.
I followed the method mentioned in the replies to relock the bootloader, i.e, flashed the fastboot rom in edl mode
But for some strange reason, when I entered the fastboot mode and checked whether the bootloader is locked or not by "fastboot oem device-info", it said "Device Unlocked: True"
The main problem came when I booted into the ROM; It broke all kinds of wireless connections. The wifi malfunctioned, the phone wouldn't read the SIM cards etc.
Is there a solution? Please help
Thanks

Phone is bugged badly.

A while back i unlocked my bootloader and installed TWRP 2.8 (via fastboot) but that was way back ago. Later i tried installing the OTA update via the phone directly which didn't work so i didn't bother as it didn't affect much. But today i was about to install a new rom but i couldn't boot into recovery(booting into recovery via advanced power options, it just didn't work anyway) I thought i might as well reflash recovery using the fastboot method again but when i used fastboot oem unlock command ( I know i used it before i thought i had to do it again im so sorry) it just flashed the one plus logo, vibrated and redid the same thing again and again with no chance of booting.....after using command fastboot continue it booted ! ( God thank you !) but the phone only boots via fastboot continue command I need to get it back to normal !
Also I checked fastboot device info, it said device unlocked and device verified =false ?!
So my BOOTLOADER is locked on its own ? plus recovery isnt available ? AND it doesn't even boot the normal way?
Im really worried now ! please assist me ?

Use the usual Qualcomm factory restore to revert everything back to working Lollipop software. From there you can try anything except OxygenOS 3.0 Beta or latest HydrogenOS without having to change to compatible recovery for those bootloaders.
Next time, at least try to use the search function, your case is nothing new and has already been answered many times over since the release of OOS3 beta and HydrogenOS Marshmallow ROM.

Can't unlock bootloader, can't finish OS setup

So I upgraded to Nougat on my P9 Lite, unlocked boot loader, used twrp, flashed roms and everything went smooth. Saw a more up-to-date version with no bugs, so I had to downgrade to MM first.
I followed a guide, but I messed up somewhere and ended up having my bootloader locked, and I can't access the OS to enable developer options and oem unlock from settings. The reason why I can't access the OS is that I am stuck in the setup. I am stuck at the part where I have to sign in to my google account. It doesn't show a keyboard, only a microphone, and I can't use that for my password (it won't let me).
Any ideas?
TL;DR messed up during downgrading from Nougat to MM, now TWLR is gone, bootloader is locked and my main issue is that when I get to the google account sign in part during OS setup, there is no keyboard (I can only use dictation) so I can't sign in... So I'm stuck
Also, can I unlock bootloader without access to OS, without being able to navigate to settings, enable developer options and then oem unlock?
1. Stuck in OS setup? Signing in to Google? Hey, it's not obligatory, can't you just skip it?
2. Flashing ROMS locked your bootloader, it's normal, but I'm sure it didn't change the "oem unlock" setting you had surely enabled before. Go to fastboot mode and check Bootloader and FRP status on the bottom of the screen. If FRP is unlocked, you will be able to unlock bootloader again.
3. If you have your TWRP gone (flashed by stock ROM), flash the recovery partition manually - fastboot flash recovery TWRP.img (download from Meticulus Project site).

It is obligatory, I couldn't skip it. I tried to use other methods of signing in, but then it asked me to reset password at the end.
Both Phone and FRP are locked
I think I have missed this, but I can't do it via fastboot because I keep getting "Command not allowed" whenever I try to unlock bootloader or do anything via fast boot.
Also, thank you so much for your time and input. It is much appreciated.
That's weird, I flashed my phone several times with different ROMS (not Nougat) and this setting (oem unlock / FRP unlocked) stayed enabled. Don't know where it sits then and how to change it without getting inside OS. But - what about TWRP? Oh right, you won't be able to flash it without unlocked bootloader... Oh, crap. I would try SRK Tool for Huawei to play with bootloader, it uses fastboot so shouldn't help, but maybe, just maybe? Maybe try flashing whole ROMs through dload folder on SD? Stock 120, 161, Nougat, I would try these. I hope there is some way to unlock FRP, probably it's possible in DC-unlocker (it's a paid software).

Yes, it's very weird. I haven't done the process a lot. But I've flashed a couple of phones I had before, went smooth. Nothing major like this happened before.
I will consider the SRK Tool and I did not know about the DC-Unlocker tool, thank you for telling me about it.
Flashing whole roms through dload folder only works with Nougat for some reason, and I keep getting stuck in the signing in problem because of no keyboard, someone told me that's incomplete software, I'm hoping that's the case, any ideas where can I get it from?
Again thank you Jagiel88 for your time and advice xD
No problem, unfortunately I haven't tried Nougat yet, so search for help on down/upgrade Nougat beta <-> Marshmallow threads .

How to Stock FW and Relock Bootloader? OP5

Hi all,
I've wanted to go back to Stock OS but when i type "fastboot oem lock" it says "FAILED <remote: Flashing Lock is not allowed."
Everything boots normally to OS 4.5.2. In DEV options the Unlock Bootloader is greyed out and says bootloader is already unlocked.
What can i do?
Cheers
These instructions did work for me with the OnePlus 3/3T. They should also work for the OnePlus5, just make sure that you download the OnePlus5 version of the software and recovery.

Hello. I first thing I do always is to install drivers. I start by connecting the phone to the laptop in charge mode, then in transfer files mode, MTP or camera. In this way he will recognise all the drivers your laptop needs.
Also I enter in fastboot mode and recovery so the laptop can recognise the drivers and always reboot laptop and phone just to double check.
What I did was: go to Developer Options and enabled Unlock Bootloader and USB Debugging.
Then I accepted the laptop request on my phone and all drives were OK.
I run CMD and typed fastboot devices to see if it recognises my phone and it displayed a serial number. So I proceed next to type fastboot oem unlock and the process went OK and on my phone it asked Yes or No to unlock and I choose yes.
Then I flash a twrp image by typing on CMD: fastboot flash recovery recovery.img (my twrp I'm had other name so I rename it. You need to enable "Show file extensions" in Windows so you can see what the extension is).
I then type fastboot boot recovery.img and the phone entered in Recovery Mode in this case TWRP.
My phone was always connected to the laptop and he open the internal storage window so I drag the supersu inside.
Then on TWRP I wiped dalvik and cache and I went to Install and installed the SupeSU on my internal memory root.
The phone then rebooted and ready to go.
But then I went to developer options and the Unlock bootloader was greyed out. I unroot my phone and flashed a stock recovery for OP5 and the stock image 4.5.2 and when I type fastboot oem lock it always says it can't be flashed.
I need to stock it since I'm giving to a family member and they don't understand much about phones and If there's a problem the warranty doesn't cover.
Just installed supersu to try an app. I never install 3rd party roms.

if your phones boots its not bricked... My guess is that you data is corrupted, i would wipe everything including userdata en reflashing the stock with recovery.

Hi right before your comment i managed lol.
I re-flash the stock recovery and in recovery i reset and wipe everything. then i install the OS4.5.3 by ADB Sideload and it's working now.
Just wanted to get rid of the inital warning that my bootloader is unlocked. I want to lock again.
I rooted my device with Magisk, and now I want to restore it to factory state.
I flashed stock recovery and OOS several times, wiped everything but fastboot oem lock failed all times (FAILED (remote: Flashing Lock is not allowed)).
Can you help me?

here in this video u can see in detail how to lock bootloader. hope this help you
https://www.youtube.com/watch?v=CQYCSdDUdAU
HOW TO RELOCK..
Install TWRP and Magisk if you don't have them yet.
Magisk should allow you to slide "OEM unlocking" to "enabled"
Reboot to fastboot
Flash stock recovery via fastboot.
Run locking via fastboot flashing lock
Allow it to reboot and upon start up it will say device corrupted (THIS IS NORMAL)
Boot to recovery via the warning start screen.
Once in recovery, sideload latest FW.
Profit.
I usually do it this way (successfully):
Wipe everything but OTG in TWRP
Format data
Reboot to TWRP
Flash the full stock OOS zip
Reboot to fastboot
Flash stock recovery
Lock bootloader with the fastboot lock command
Has anyone made any progress with this? I too am having the issue as described and have tried the solution by Ricyksydhu, along with solutions from various other places around the net.

How to lock bootloader on latest stock oreo (A2017G)?

I am attempting to return my Axon 7 A2017G to complete stock so that I can use the warranty. I used the EDL tool to return to latest stock oreo, but it seems that there is no way to access fastboot/bootloader on this update. I've found many guides for other models or older versions on how to get fastboot but none of them seem to be specific to my model and I am not than keen on bricking my device again. Could anyone help me out on what process I should go through to be able to lock my bootloader?
This is the EDL package I flashed: A2017G_B03_OREO_FULL_EDL

I'm not even sure if you can lock the bootloader in stock+ Oreo, but it should be possible. What you can do is go back to MM (MM B10 should be fine), then use a fastboot package for MiFlash (such as A2017U_FASTBOOT_UNLOCK_EDL, it works even though you have a G) or maybe check if EDL Tool has an option to install fastboot, i don't remember.
The other way around it is not locking it and just using a modified bootloader to conceal the 5 second screen. Good enough for sending the phone with warranty. If you'll sell it you might be able to sell it for more if the bootloader is unlocked

Thanks I checked the Axon 7 Toolkit and turns out it does have fastboot unlock as part of the process of unlocking the bootloader. Though it techinically doesn't support Oreo I chose the nougat one and it still did the trick albeit with another hardbrick, once locking the bootloader I had to wait for the battery to drain again before I could get into EDL and flash back to Oreo. Very painful proccess, would not recommend, should have just used your method of going back to marshmallow locking then updating again. Thanks anyway mate, the help was much appreciated.

I never mentioned the axon7toolkit. That one is finicky, I don't recommend it. I was talking about EDL Tool (you might even find it if you google it), it's here in the ROMs, kernels, development section.

you need to flash original stock rom for your device trough edl. (rom your device came from factory,you need B11 marshmallow)
then boot into system,unlock developer options.Allow oem unlock and turn on usb debugging.Now connect phone to laptop and check the dialogue on your phone that ask for usb debug.Unplug phone.
When you did this you want to flash TWRP trough EDL.
Now boot in TWRP and flash UnlockbootloaderPackage from DrakenFX.
Reboot system.
Now turn off your device and boot into fastboot,connect your phone with laptop and open ADB terminal on your laptop or use Axon7toolkit.
In terminal enter fastboot oem lock,or in axon7toolkit choose lock bootloader.
Your bootloader is now locked.
PS: you dont need locked bootloader to recieve ota's,and make sure you are on the firmware your device came shipped with!!

you need to flash original stock rom for your device trough edl. (rom your device came from factory,you need B11 marshmallow)
then boot into system,unlock developer options.Allow oem unlock and turn on usb debugging.Now connect phone to laptop and check the dialogue on your phone that ask for usb debug.Unplug phone.
When you did this you want to flash TWRP trough EDL.
Now boot in TWRP and flash UnlockbootloaderPackage from DrakenFX.
Reboot system.
Now turn off your device and boot into fastboot,connect your phone with laptop and open ADB terminal on your laptop or use Axon7toolkit.
In terminal enter fastboot oem lock,or in axon7toolkit choose lock bootloader.
Your bootloader is now locked.
